101-year-old nutrition prof’s seven health rules that have me questioning everything

Right, a 101-year-old professor who’s sharper than your nan’s knitting needles, still driving, and jetting about, has shared how he’s managed to live this long. No, he’s not secretly a vampire. His name’s Dr John Scharffenberg, and he’s got rules. Seven of them. And honestly? They’re making me question every snack I’ve ever eaten. The man’s lived through world wars and still won’t touch a biscuit. It’s basically everything every other health influencer says… except this guy’s actually 101. So we’re listening.

1. Don’t puff, ever

Not even once. Dr John’s never touched a cig in his life. Thinks smoking is an absolute no-go and, let’s be real, he’s not wrong. Cigarettes are grim. It wrecks your lungs, messes with your heart, and makes your breath smell like a bonfire gone wrong. So if you’re still sneaking off for a cheeky puff—don’t.

2. Bye Bye booze

Umm… You can have absolutely no alcohol. Not even a tiny glass of red with dinner. Dr John isn’t buying the “wine is good for your heart” argument. He reckons if you’re drinking, even a little, you’re not doing your body any favours. Too much? Maybe. But he’s 101, so maybe he’s onto something. Just don’t take our pint away, mate.

3. Sugar is the enemy

If you’ve got a sweet tooth, you might want to look away. Dr John even tweaks recipes just to dodge it. His view? Sugar’s a sneaky villain linked to heart disease, weight gain, and dodgy teeth. Still, saying goodbye to chocolate feels… tragic.

4. Exercise like you mean it

Even though he’s a nutrition whizz, Dr John reckons exercise is the real MVP. Especially between the ages of 40 and 70, so no more “I’m too tired” excuses. Time to dust off the trainers and move your limbs.

5. Watch your weight

Weight isn’t about chasing a six-pack, it’s about keeping steady, says the prof. He’s a fan of intermittent fasting and big plates of wholesome, unprocessed grub. Basically: No more sneaky snacks. This one’s gonna be hard to swallow (no pun intended).

6. No meat, please

He’s been off meat since he was 20—TWENTY! Instead, he’s all about plants: Fruit, nuts, seeds, and the occasional egg and glass of milk. Not full vegan, but definitely plant-first. Crying in Spoons with a full English breakfast.

7. Saturated fat? Nuh-uh

Cheese lovers, this one is for you. Saturated fat is last on Dr John’s list but definitely not the least. He reckons it’s a one-way ticket to high blood pressure, dodgy cholesterol, and all sorts of health drama. But, er, cheese. And butter. Ugh, I’m gonna miss you.

Honestly, part of me wants to applaud the man, and part of me wants to cry into a burger. No smoking, no drinking, no sugar, no meat, what’s left? It’s the same old health advice we’ve heard a million times, but Dr John’s got that extra bit of cred to make you stop and think. He’s still sprightly, and loving life. Maybe he’s not so mad after all.

But also, can we please just live a little?
